      • This fix checks both global wsrep_on and wsrep_provider values to determine if wsrep processing should happen

  • Revision #d45b582 2016-04-02 22:37:22 -0300
    • MW-259 - moved wsrep desync/resync calls from wsrep_desync_update() to wsrep_desync_check() method which does not hold the lock and is arguably a more fitting place to change provider state - before changing the actual variable value.
  • Revision #4582a4b 2016-08-12 14:03:24 -0400
    • Fix galera_ist_recv_bind.test.

      • test case for this anomaly
  • Revision #d246630 2016-03-07 23:34:03 +0200
    • Refs MW-252 - changed the condition when to do implicit desync as part of FTWRL to cover only case when node is PC and synced. Donor node has alreaydy desycned and other states mean that node is not in cluster, so desync is not even possible.
  • Revision #f3444c4 2016-03-04 14:20:58 +0200

  • Revision #8ec50eb 2016-02-29 22:54:58 +0200
    • Refs MW-252 - reverted from tracking donor servicing thread. With xtrabackup SST, xtrabackup thread will call FTWRL and node is desynced upfront - Skipping desync in FTWRL if node is operating as donor
  • Revision #b159b66 2016-02-29 16:36:17 +0200
    • Refs MW-252 - Calling FTWRL two times in a row caused desync error, this is fixed by making sub-sequent FTWRL calls bail out before wsrep operations
  • Revision #4290117 2016-02-29 15:24:06 +0200
    • Refs MW-252 - enveloped FTWRL processing with wsrep desync/resync calls. This way FTWRL processing node will not cause flow control to kick in
      • donor servicing thread is unfortunate exception, we must let him to pause provider as part of FTWRL phase, but not desync/resync as this is done as part of donor control on higher level
